INTEL E3845 display issue

[HLin]

We have developed a model of INTEL E3845's main board, DDI does not use, the display use VGA 。then In theory DDI compensation resistance can disable, but if it disable，it will appear under the UBUNTU system, change the resolution, the system screen is not displayed and can not return.

In the WIN7 system,change the resolution is normal. Why does the DDI compensation resistor affect the display of VGA, and only the issue appear under the UBUNTU system?
